ACS #0011 Application Case Study w w w.ardentconcepts.com Replacing SMP’s with TR for 12Gsps ADC Engineers working on a test team at a major IC manufacturer were developing next gen, JESD204B standard data converters, Digital to Analog (DAC) and Analog to Digital (ADC) running at 12GSPS with plans to increase speeds. Their test team used surface mount SMPs for characterizing their channels. This was accomplished by fanning out traces to SMPs on their test boards. For a typical program they would use 32 SMPs per board with more than 40 boards manufactured per program. This meant up to 1,200+ nonrecoverable SMPs were a sunk cost at the end of each program. Adhering to JESD204B, the company was looking to reduce the number of interconnects and therefore realize a smaller form factor.
